New Reference Boards That Management Rotary Fridge Compressor Drives

The compact boards present easy-to-use energy stage, good light-load effectivity and scale back footprint whereas bettering reliability

Designed for rotary fridge compressors, listed here are two new reference boards by Infineon Applied sciences AG for low-power compressors. These might be simply used for constructing last mass-production software boards, enabling product builders to drastically scale back the system improvement time.

The REF_Fridge_D11T_MOS is a ready-to-use three-phase inverter together with the iMOTION Sensible Driver IMD111T-6F040 and the 600 V CoolMOS PFD7 superjunction MOSFET IPN60R1K0PFD7S. The board supplies an easy-to-use energy stage based mostly on the iMOTION sensible driver that mixes ready-to-use FOC motor management algorithms with a 600 V part gate driver within the LQFP-40 bundle. It additionally consists of the discrete CoolMOS superjunction MOSFET with lowest Q rr, ESD safety and a compact SOT-223 floor mounted gadget (SMD) bundle. The board might be simply interfaced by way of iMOTION Hyperlink and allow the very best light-load effectivity in addition to a compact design.


The reference design REF_Fridge_C101T_IM231 is good for patrons aiming for a better stage of integration and a diminished footprint. The board combines a digital motor management IC (iMOTION) IMC101T-T038 with a three-phase CIPOS Micro clever energy module based mostly on a 6 A, 600 V IGBT. This mixture supplies a fully-featured compact inverter resolution for low energy motor drive purposes. Moreover, it reduces BOM depend and PCB dimension whereas bettering reliability.


With these options, Infineon stands true to its motto “From product pondering to system understanding.” The REF_Fridge_D11T_MOS and the REF_Fridge_C101T_IM231 at the moment are obtainable.
